VM 26 Issues
Okay been trying to dial in this carb to no avail, so wanted to see if the carb gurus can chime in.
Background airbox mod with K&N filter, Ebay exhaust, valve lash just reset after 100 miles to .03/.04., i am at 600-700ft elevation. Mikuni carb is jetted with 27.5 pilot with 120 main needle on center notch. All seems to run good except when i am in the WOT position, it will pull but then hesitate and pull again like its cutting out? now after i return from a ride when i stop the idle will drop low and engine will die, but will restart no problem. I am no carb guru hell it took me 2 months to dial in my harley, but this one has me baffled as to which way to go?

As far as dying out when you come to a stop, what is your idle mixture screw set at?n Sounds like it may be also a bit rich on that circuit as well. EDIT: Just to emphasize this point. Make sure to wait until the bike is fully up to temp before making any notes on the change of the tune.

Now still got the idle issue with the 27.5 i have been at 1 1/4 ,1 1/2 and 1 3/4 turns out , now when i finish my ride i can stop and idle is normal for about 30 secs to a minute then it dies??? but it does idle down and stumble right before it does. Edit: i did have a 25 pilot in and recommendation was to increase size due to it stalling when blipping the throttle

Try the idle mixture at 1 turn out. If that doeant help, go back to the 25.
